What I love about this place is that it is comfortable to stay in - clean, airconds are well-maintained, there's a washer with a small balcony to dry your clothes, hot shower, fast internet (with Netflix!) and a comfortable bed. It is central as the Sukhumvit MRT is just outside the unit and the Asok BTS 100m away.
What's a small setback is that the property does not allow "day rentals". However, I was not disturbed throughout my 8 days there. Just walking in like a boss!
Here are some things I found useful:
1. There is a 7-11 about 100m walk by using the side entrance at the back of the building.
2. You can walk to the Asok BTS station (away from the sun/rain) by accessing the Sukhumvit MRT station and then walking through the Metro Mall.
3. If you plan to use the BTS frequently, buy the Rabbit card at any BTS station for THB100 (nonrefundable). Top-ups are in the denomination of THB100s. You cannot use the Rabbit card on the MRT line.
4. Health Land (decent massage) is just about 7mins walk. Just Google Map it.
5. If you plan to go the Survarnabhumi International Airpot using the Grab app, type in "BKK airport" to find the destinations. I couldn't find it if I typed "Survarnabhumi Airport" for some reason.
